First the case of the Google executive found dead on his yacht. Expensive escort has been charged with giving him an overdose of heroin and security cameras showing him stepping over him and sipping a glass of wine on her way out. Cecilia Vega has the story. Reporter: We are learning more about her side of the story. Tichelman's lawyer says she had no intention of harming that executive. Police are telling a different story and want to know if there's more victims out there. She is the alleged high-priced call girl accused of killing a Google top executive. This morning Alix tichelman is behind bars saying the whole thing was an accident. I don't believe this was an intentional crime. This case is about two adults engaged in mutual consensual drug usage. Reporter: Forrest Hayes was found dead last November. Police say surveillance footage from an onboard camera shows tichelman helping the father of five inject himself before he collapses. They say he can be seen stepping over his body and finishing her glass of wine. She did nothing to show concern, any care. Reporter: Now investigators are poring over her internet accounts and the 200 prostitution clients she allegedly boasted about searching for more potential victims. Is there somebody out there who had a near-death experience or managed to survive this. Reporter: Police wonder if 53-year-old dean realpelt did not escape. My boyfriend overdosed. ? Just released 911 tapes she said dean has just collapsed but she repeatedly hangs up on operators. Is he awake? He is -- no, not really. Is he breathing? Yeah, he's breathing, like he's not -- I don't think he's going to die. He scared me. Reporter: Atlanta police had ruled his death accidental unlike Hayes' death back in California where tichelman is now being held on $1.5 million bail. And tichelman's postings online will be key for police. Now, they say they tracked her down by pretending to be a client and her goal was to spend a lavish weekend with a wealthy man and say she charged more than $1,000 per customer. George, she's now facing charges that include manslaughter, possession and prostitution. Cecilia, thanks very much. Let's bring in Dan Abrams. It's not a slam dunk case. She's charged with voluntary manslaughter. Typically that is heat of passion or a fight. To prove voluntary manslaughter in this case they'll have to still demonstrate that she had the intent to create serious injury. The defense says, look, we were doing drugs together. I didn't have any intent to do anything wrong here. So I think that this is a play by prosecutors to try to get her to plead to involuntary manslaughter meaning to say, look, we'll cut a deal because it seems like based on what we know right now, it seeps much more like a possible involuntary manslaughter case. As a result the sentence would be lower. How about the overdose of the former boyfriend? Will prosecutors bring that into the case? They have to figure out if it was an overdose or something else. If it was just an overdose, they may not be able to and probably won't be able to. If they can somehow demonstrate that in that case, she was responsible in some sort of criminal way, then they might be able to introduce that. Finally that security video they say they have of her being very callous, just ignoring the body. So powerful in front of a jury. Bring that video in front of a jury and say, look what she's doing. She didn't care yet when you think about the actual charge here, the question is, is it really legally relevant? It's going to come in but I don't know it should be that important legally what she did after the fact. They're not suggesting she murdered him. They're not saying she wanted to -- him to die and then she callously walked out. Even prosecutors at this point are saying, she may not have intended to kill him and I think that's why the after the fact behavior shouldn't be that important. Dan Abrams, thanks very much.
